XSD 1.1 - cannot validate with conditions

[tutucek7]

Hello, I'm trying to use conditions in my XSD, because of different tags in elements.

<xs:element name="a" maxOccurs="unbounded">
<xs:alternative test="@type = 1" type="a1Type"/>
<xs:alternative test="@type = 1" type="a2Type"/>
</xs:element>
<xs:complexType name="a1Type">
<xs:sequence>
<xs:element name="name" />
<xs:element name="surname" />
</xs:sequence>
</xs:complexType>
<xs:complexType name="a2Type">
<xs:sequence>
<xs:element name="name" />
<xs:element name="id" />
</xs:sequence>
</xs:complexType>

When i will drop that to W3C validator, it's valid. But in VS code with your extension not. It says this: s4s-elt-must-match.1: The content of 'a' must match (annotation?, (simpleType | complexType)?, (unique | key | keyref)*)). A problem was found starting at: alternative.

I think it is because we use Xerces which cannot support XSD 1.1.

I think it is because we use Xerces which cannot support XSD 1.1.

So is there anything what can we do?

I worked long time ago to support XSD 1.1 in eclipse-lemminx/lemminx#515 but it is uses a non official Xerces version, I fear that there is no solution for the moment while Xerces doens't support XSD 1.1.
